AIHW - National Cancer Screening - Participation in the National Bowel Cancer Screening Program (SA3) 2014-2017

This dataset presents the footprint of participation statistics in the National Bowel Cancer Screening Program (NBCSP) for people aged 50 to 74. The NBCSP began in 2006. It aims to reduce morbidity and mortality from bowel cancer by actively recruiting and screening the eligible target population for early detection or prevention of the disease. The data spans the years of 2014-2017 and is aggregated to Statistical Area Level 3 (SA3) geographic areas from the 2011 Australian Statistical Geography Standard (ASGS).\n\nCancer is one of the leading causes of illness and death in Australia. Cancer screening programs aim to reduce the impact of selected cancers by facilitating early detection, intervention and treatment. Australia has three cancer screening programs:\n\n * BreastScreen Australia\n\n * National Cervical Screening Program (NCSP)\n\n * National Bowel Cancer Screening Program (NBCSP)\n\nThe National cancer screening programs participation data presents the latest cancer screening participation rates and trends for Australia's 3 national cancer screening programs. The data has been sourced from the Australian Institute of Health and Welfare (AIHW) analysis of National Bowel Cancer Screening Program register data, state and territory BreastScreen Australia register data and state and territory cervical screening register data.\n\nFor further information about this dataset, visit the data source:[Australian Institute of Health and Welfare - National Cancer Screening Programs Participation Data Tables](https://www.aihw.gov.au/reports/cancer-screening/national-cancer-screening-programs-participation/data).\n\nPlease note:\n\n * AURIN has spatially enabled the original data.\n\n * Participation rates represent the percentage of people invited to screen through the NBCSP during the relevant 2-year period, who returned a completed screening test within that period or by 30 June of the following year. The number of individuals invited to screen excludes those who deferred or opted out without completing their screening test.\n\n * Values assigned to n.p. in the original data have been set to null.\n\n * SA3 areas were assigned to NBCSP invitees using an SA2 to SA3 correspondence, which may lead to some minor inaccuracies in results.\n\n * Some invitee SA2 codes and postcodes cannot be attributed to an SA3. These invitees were included in an 'Unknown' group where applicable.\n\n * Biennial screening for those aged 50-74 is not fully rolled out. During the time period reported, the specific ages invited within the 50-74 age range included 50, 54, 55, 58, 60, 64, 65, 68, 70, 72 and 74.\n\n * These results calculate participation rates using the new NBCSP performance indicator specifications. This indicator now measures a 2-year invitation period and also excludes those who opted off or suspended participation. Therefore, these results cannot be compared to rates reported prior to 2014.\n\n * NBCSP participation rates per area are not related to bowel cancer incidence rates.\n\n * SA3 areas with a numerator less than 20 or a denominator less than 100 have been suppressed.\n\n * SA3 data for the Blue Mountains - South, Christmas Island, Cocos (Keeling) Islands, Cotter - Nimadi, Fyshwick - Pialligo- Hume, Illawarra Catchment Reserve, Jervis Bay and Lord Howe Island were suppressed due to reliability concerns from low numbers in these regions.\n\n * The 2014-2015 period covers 1 January 2014 to 31 December 2015, the 2015-2016 period covers 1 January 2015 to 31 December 2016, and the 2016-2017 period covers 1 January 2016 to 31 December 2017.\n\n * The number of people in different SA3s may not sum to 'Australia' total due to rounding.\n

本数据集展示了针对50至74岁人群的全国肠癌筛查计划（National Bowel Cancer Screening Program, NBCSP）的参与统计概况。该计划于2006年启动，旨在通过主动招募符合条件的目标人群并开展筛查，实现肠癌的早诊早治或疾病预防，从而降低肠癌的发病率与死亡率。本数据集涵盖2014至2017年的数据，并按照2011年澳大利亚统计地理标准（Australian Statistical Geography Standard, ASGS）中的三级统计区域（Statistical Area Level 3, SA3）进行聚合。

癌症是澳大利亚致病与致死的主要原因之一。癌症筛查计划旨在通过推动早诊、干预与治疗，降低特定癌症的危害。澳大利亚目前共有三项国家级癌症筛查计划：

* 澳大利亚乳腺癌筛查项目（BreastScreen Australia）

* 全国宫颈癌筛查计划（National Cervical Screening Program, NCSP）

* 全国肠癌筛查计划（National Bowel Cancer Screening Program, NBCSP）

本国家级癌症筛查计划参与数据展示了澳大利亚三项国家级癌症筛查计划的最新筛查参与率及发展趋势。该数据源自澳大利亚卫生与福利研究所（Australian Institute of Health and Welfare, AIHW）对全国肠癌筛查计划登记数据、各州及领地的澳大利亚乳腺癌筛查项目登记数据，以及各州及领地的宫颈癌筛查登记数据的分析。

请注意：

* 澳大利亚城市研究基础设施网络（Australian Urban Research Infrastructure Network, AURIN）已对原始数据完成空间适配处理。

* 参与率指在相关两年期内受邀参与全国肠癌筛查计划的人群中，于该周期内或次年6月30日前完成筛查检测的人数占比。受邀筛查的人数不包括已推迟筛查或未完成检测即退出的人群。

* 原始数据中标记为‘n.p.’的数值已被统一设置为空值。

* 本次研究通过二级统计区域（Statistical Area Level 2, SA2）与三级统计区域（SA3）的对应关系，将全国肠癌筛查计划的受邀者分配至对应SA3区域，这可能导致结果存在细微偏差。

* 部分受邀者的二级统计区域编码与邮政编码无法匹配至对应的SA3区域，此类受邀者将被归入‘未知’组别（如适用）。

* 针对50至74岁人群的两年一次筛查尚未完全推广。在本次报告的时间段内，50至74岁年龄组中受邀接受筛查的具体年龄为50、54、55、58、60、64、65、68、70、72及74岁。

* 本次结果采用全国肠癌筛查计划最新的绩效指标规范计算参与率。新指标以两年为邀请周期，同时排除已退出或暂停参与筛查的人群，因此本次结果无法与2014年之前公布的参与率进行对比。

* 各区域的全国肠癌筛查计划参与率与肠癌发病率并无关联。

* 若某SA3区域的参与率计算分子（完成筛查检测人数）小于20，或分母（受邀筛查人数）小于100，则该区域数据已被隐去。

* 蓝山南部、圣诞岛、科科斯（基林）群岛、科特-尼马迪、菲什威克-皮亚利戈-休姆、伊拉瓦拉集水区保护区、杰维斯湾以及豪勋爵岛的SA3区域数据，因该区域样本量较低导致可靠性存疑，已被隐去。

* 2014-2015周期指2014年1月1日至2015年12月31日，2015-2016周期指2015年1月1日至2016年12月31日，2016-2017周期指2016年1月1日至2017年12月31日。

* 由于存在四舍五入处理，各SA3区域的人数总和可能与‘澳大利亚全国’总计值不完全一致。
